Specification of Letters Patent.

Patented April 17, 1906.

Application filed une 26, 1905. Serial No. 267,054.

To all whom, it may concern:

Be it known that I, ERNST BERGER, a subject of the King of Wurtemberg,Germany, residing at Rorschach, in the Republic of Switzerland, haveinvented new and useful Improvements in Shuttles for Embroidering-Machines, of which the following is a specification.

This invention has relation to shuttles for embroidering-machines, andmore particularly to features of construction of such shuttles to adaptthem to be mechanically filled or filled and threaded by means formingthe subject-matter of another application for patent of even dateherewith, Serial No. 267,053.

In my application last referred to I have shown and described mechanismfor filling shuttles for embroidering machines comprising, among otheressential features, a revoluble spindle on which the thread or fillingis wound, such spindle being introduced into the shuttle through anaperture in its rear wall, and is withdrawn from the shuttle after thecop of thread has attained a given diameter. In order that the threadmay be properly wound on the spindle, it is necessary that the shuttlebe provided with a suitable aperture or slot of such length as to admitof the traversing of the thread along the rotating spindle through themedium of a reciprocating or vibrating thread-guide.

The object of this invention lies in the construction of a shuttleadapted to be mechanically filed, as above set forth.

The accompanying drawings show a form of construction of the inventionby way of example, in which- Figure 1 is alongitudinal section, and Fig.2 a rear view. Fig. 3 is a longitudinal section; and Fig. 4 an end viewthereof, showing one side wall cut away. Fig. 5 is a plan, and Fig. 6 anend view showing the cover a cut away at one side.

The shuttle for embroidering machines shown is of ordinary form, butprovided at its rear with an opening b, which has for its object torender possible the insertion of a spoolspindle into the shuttle, andthereby the winding of a spool (ball or bobbin) in the shuttle itself.The shuttle has, further, in one of its side walls a slot 0, which runsin the longitudinal direction of the shuttle. This slot is to renderpossible the guiding to and fro on the spool-spindle of the thread to bespooled.

Instead of being provided with the slot 0 the shuttle could also beprovided with another opening c in the wall. Further, the cover a could,for example, be out way on one of its long sides, as at 0 Fig. 5, or oneside wall along its free edge have a cut-away part reaching below thecover, as at c, Fig. 3.

Having now particularly described and as certained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. A shuttle for embroidering machines adapted to bemechanically filled, said shuttle having a rear end wall provided withan axial aperture forming a bearing for the reception of a revoluble copor bobbin winding spindle and serving also as a means for stripping thebobbin formed within the shuttle from said spindle, said shuttle alsoprovided with a thread-feed slot parallel to its longitudinal axis andof such length as to admit of the traversing of the thread along thespindle in the formation of the cop.

2. A shuttle for embroideringmachines adapted to be mechanically filled,said shuttle having a rear end wall provided with an axial apertureforming a bearing for the reception of a revoluble cop or bobbin windingspindle and serving also as a means for stripping the bobbin formedwithin the shuttle from said spindle, said spindle provided in one ofits side walls with a thread-feed slot parallel to its longitudinal axisand of such length as to admit of the traversing of the thread along thespindle in the formation of the cop, said slot merging into theaforesaid spindle-bearing, for the purposes set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

- ERNST BERGER.
